The ALD-2I plugs into one full option slot in the MOM-2 or
MOM-4 card cage.
This equipment is approved for operation over the tem-
perature range of 0°C and 49°C.
Engineer and Architect Specifications
Intelligent analog device circuits shall be provided by an
ALD-2I Analog Loop Driver Module. This module shall
plug into one full slot of the MOM-2 or MOM-4 card cage
as a part of the Cerberus Pyrotronics MXL or MXLV sys-
tems.
Each ALD-2I shall provide two circuits. Each of these
circuits shall support the use of up to 60 intelligent de-
vices, as well as remote conventional initiating zone
modules. Sensitivity of any smoke detector can be
queried and adjusted from, as well as displayed at, the
control panel. Sensitivity change shall be performed either
manually or automatically through the time based logic.
The ALD-2I shall support the use of relay bases, audible
bases, and remote lamps.
ALD-2I circuits shall be capable of being wired to meet the
requirements of either NFPA Style 4 or Style 6. When wired
as a Style 4 circuit, it shall support the use of parallel
branch circuits (T-Tapping).
The ALD-2I shall utilize an on board CPU as well as
network interface circuitry and A/D converters. It shall be
capable of operation in a degrade mode in the event of
MXL main processor failure or loss or network communica-
tion link. In the degrade mode the ALD-2I circuits shall be
capable of sensing an alarm condition from its connected
devices and activating local notification appliance circuits
through a degrade alarm bus.
ALD-2I circuits shall meet the requirements of NEC 760 for
power limiting.
Electrical Specifications
ALD-2I Electrical Ratings
1. Electrical Ratings
Supervisory 28 VDC peak, 60mA max
Alarm 28 VDC peak, 60mA max
(60 devices in alarm)
2. All wiring must be in accordance with Article 760 of NEC
and local building codes.
3. Only the devices in the following list may be used. A
maximum of 60 devices (excluding CZM-1, LIM-1 and
ICP) in any combination my be connected to a single
loop. The UL identifiers for compatibility are the same as
the model names specified below.

4. No end of line device is required.
5. Both circuits are power limited to NFPA 70, per NEC
760. Each detector, or group of detectors, requires a
two-wire circuit of 18 AWG minimum thermoplastic
fixture wire enclosed in a conduit of 18 AWG limited-
energy shielded cable without conduit, if permitted by
local building codes.
6. Total circuit resistance must not exceed 100 ohms.
Maximum Capacitance:
0.4µF, between loop+ and loop-
0.8µF, between loop+ and chassis
0.8µF, between loop- and chassis
7. T-Tapping is not allowed on Class A loops.
